Clamshell crane is due to manipulation of the grab bucket opening and closing, the crane needs to have two sets of corresponding traction mechanism, usually adopts double drum winch to separate support grab opening and closing and displacement. While the hook crane only needs a set of traction mechanism to achieve the displacement of the hook is enough, without the need to configure a dual-roll winch. However, if it is a double crane with its own configuration of the crane type, it is a different matter.J4PHenan Dongqi Machinery Co., Ltd
